The study carried out on Z. zanthoxyloids and Z. macrophylum, lays on the program of valorizing phytogenetical resources. It covers monographic and phytochemical study. Inner uses of these resources show as well their importance on the scale of such African countries as Nigeria, Togo, Congo, Ivory Coast, Central African Republic, Benin, Senegal and Mali. Z. macrophylum is the most used species in the treatment of rheumatism. Over all the inner practices, Z. zanthoxyloids is the most used species. Analysis in multiple correspondences (AMC) with a partial contribution of 80% shows that there is a correlation of uses over all countries, except Senegal that has specific uses. Total extracts obtains from the two specific species from the Central African and Togolese flora have various yielding according to different organs.
